Pedigree Collapse
In genealogy, pedigree collapse describes how reproduction between two individuals who share an ancestor causes the number of distinct ancestors in the family tree of their offspring to be smaller than it could otherwise be. Robert C. Gunderson coined the term; synonyms include implex and the German '' Ahnenschwund'' ("loss of ancestors"). Overview Without pedigree collapse, a person's ancestor tree is a binary tree, formed by the person, the parents (2), the grandparents (4), great-grandparents (8), and so on. However, the number of individuals in such a tree grows exponentially and will eventually become impossibly high. For example, a single individual alive today would, over 30 generations going back to the High Middle Ages, have 230 or roughly 1 billion ancestors, more than the total world population at the time. This paradox is explained by shared ancestors. Instead of consisting of all different individuals, a tree may have multiple places occupied by a single individu ...

Genealogy
Genealogy () is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography. The record of genealogical work may be presented as a "genealogy", a "family history", or a " family tree". In the narrow sense, a "genealogy" or a " family tree" traces the descendants of one person, whereas a "family history" traces the ancestors of one person, but the terms are often used interchangeably. A family history may include additional biographical information, family traditions, and the like. The pursuit of family history and origins tends to be shaped by several motives, including the des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Born in Madrid at El Escorial, Ferdinand was heir apparent to the Spanish throne in his youth. Following the 1808 Tumult of Aranjuez, he ascended the throne.

A revolt in 1820 led by Rafael del Riego forced him to restore the constitution, starting the Trienio Liberal, Liberal Triennium, a three-year period of liberal rule. In 1823 th ...
